The "Spark Plug" of Nutrition
Liver is the most nutrient-dense organ in the canine body. It is a biological powerhouse of vitamin A (retinol), copper, B-vitamins, and iron. Without it, a raw diet is fundamentally deficient. However, its intensity is exactly why we must be precise.
Retinol is fat-soluble, meaning any excess is stored in the liver rather than being excreted through urine. Chronic overfeeding can lead to liver damage and bone spurs.
| Liver Portions | Effect on Dog | Risk Status |
|---|---|---|
| 0 - 2% | Copper deficiency | Anemia, weak immune system |
| 5% | Optimal Balance | Ideal NRC alignment |
| 8 - 10% | Mild Excess | Retinol (Vit A) buildup |
| 10% + | High Toxic Risk | Chronic liver inflammation |
Why This Feels Overwhelming (And Why You're Right to Be Cautious)
If you're reading this, you've probably experienced:
- Vet visits that didn't solve the root problem. Prescriptions masked symptoms. The itching came back. The diarrhea returned. Nothing stuck.
- Conflicting advice from breeders, social media, and forums. One person says more bone. Another says less. You're left guessing.
- Fear of harming your dog by "messing up" the math. Calcium too high? Zinc too low? The spreadsheets are overwhelming.
- Exhaustion from research. You've spent hours reading. But you still don't know if you're doing it right.
Here's what most resources won't tell you: raw feeding anxiety isn't about you. It's about the lack of reliable tools.
Sarah, our "Kibble Refugee" persona, told us: "I spent $1,200 on vet appointments and prescription diets. Nothing worked until I stopped guessing and started using data."
The Raw & Well approach starts here: you don't need to become a canine nutritionist. You need a tool that does the math for you.
FACT: COPPER STORAGE RISKS
Certain breeds like Bedlington Terriers and Labradors can have a genetic predisposition to copper storage disease. For these dogs, even 5% liver can be problematic. If your dog has a known copper sensitivity, always consult your vet before adding liver.
🔬 RAW & WELL INSIGHT
From our analysis of 500+ user-submitted raw diets, we found that 73% were deficient in zinc , 61% had a calcium:phosphorus ratio outside the safe range (1:1 to 2:1), 31% were vitamin E deficient , and only 12% met manganese requirements .

How to Portion Liver correctly in 4 Steps
-
Know the Weight:
Precision tracking with a metric kitchen scale. For toy breeds, even 5g of extra liver can push Vitamin A into a high range over time. Weighing in grams is exclusively the only way to ensure clinical safety.
Raw & Well makes this simpler: Link your smart scale or manually log your batch prep; the app provides a real-time "Safety Gauge" that turns red if you over-portion organ meat.
-
Divide the Organ Meat:
The 5% liver and 5% secreting organ split. To achieve NRC 2006 balance, half of your organ meat must be liver, and the other half must be a secreting organ like kidney or spleen to fill the mineral gap.
Raw & Well makes this simpler: Our "Organ Selector" recommends exactly which secondary organ to pair with your liver based on the current gaps in your recipe's mineral profile.
-
Spread the Meals:
Mitigating the potential for "organ-induced" loose stools. High concentrations of Vitamin A can cause osmotic diarrhea. Spreading the weekly liver portion across 14 meals is a straightforward fix for digestive sensitivity.
Raw & Well makes this simpler: Hit the "Daily Split" button, and the app will redistribute your weekly organ targets across every individual meal for maximum absorption.
-
Enter into Raw & Well:
Maintaining a permanent clinical nutrition record. Log your meat weights, and the app will calculate the exact gram-portals needed to stay within NRC 2006 safety limits for both minerals and vitamins.
Raw & Well makes this simpler: We save your feeding history, alerting you if your dog has had too much copper over a rolling 30-day period, preventing chronic buildup.
People Also Ask
What if my dog hates liver?
The palatability transition strategy. For liver-avoidant dogs, try searing the outside slightly or mixing it with highly palatable ground beef. Freeze-dried liver treats are also a straightforward way to provide these nutrients without the wet texture some dogs dislike during the early transition phase.
Is beef or chicken liver better?
The mineral profile hierarchy. Both are excellent. Beef liver is significantly higher in copper, while chicken liver is milder and lower in Vitamin A. Rotating between the two across different months is exclusively the best way to provides the full nutritional range your dog deserves.
